When I turn on power to the boat the lights around the buttons automatically come on but screen stays completely black. If it boots I can’t see it. Noticed that this is intermittent. Some times it...

Guys I haven’t called humminbird yet thought I would check here first. Humminbird solix 12 g2. Lights around buttons come on without me hitting the power button and the screen stays black. This is...

Got it. It was binding just slightly dropped lower unit put it in forward gear and reinstalled. Smooth now. Thanks everyone for the input

Ok guys it’s back together and goes in forward and reverse fine but isn’t smooth. Has a little crunch to it when running. When not running and you put it in gear you have to rotate prop just barely...

Guess I should have added that it was in Neutral at the time it came out. It doesn't turn freely by hand so I know that it is back in the teeth when I dropped it back in.

2017 optimax pro xs 250. Serial #2B401289 Guys I have a leak in the lower unit around the shift shaft seal. I decided just to replace the seal and housing. When I removed the housing the shift shaft...

I have look under the flywheel and everything looks clean nothing obvious. Like mentioned before the motor was running but has been sitting for years. I did however remember I believe the last time...

Verified TDC it’s right on the mark. Also spark is gone again completely. Frustrating

I will add when i plug shift switch back I still have fire only on Cylinder #2 but when I plug the kill switch back going to powerpack Black/orange and Black/white I lose spark again completely. I...

Ok more confused now than before. I disconnected kill switch and shift interrupt switch and got fire on cylinder #2. I checked both switches and they seem to be working as they should but when I plug...

Best place to download service manual online? I have been through the testing and still no fire. I would guess work from the stator back to the coils now troubleshooting?

Ok wouldn’t unplugging switch and jumping it over do the same thing with regard to the black/yellow? Even by the diagram I don’t see 2 black/yellow going directly to powerpack. Maybe manual will shed...

So disconnected switch and spun engine from solo if to starter. Also disconnected black/yellow and black/orange going directly to power pack no spark

Ok guys I have a 1996 225 Johnson venom that doesn’t have fire to any cylinders. Back story is this motor was running but has sat for ten years. Motor turns over fine. Tank has been drained and all...

So I’m just the unlucky one? I’m going to repower the boat at the end of the year just don’t want to rebuild it again between now and then if possible

I was told that it was sent to a machine shop where they heated the block and replaced cylinder #1 with an oversized sleeve. Could heating the block be what has caused now cylinder #2 to rotate? I...

You guys going to love this. So 6 Months after rebuild due to sleeve rotation in cylinder 1 now cylinder 2 has rotated. Back to rebuild again. So question I have owned the boat since day one. This...

Ok gentlemen boat is back. Ended up at 3700 to have the sleeve repairs and engine put back together. Still worth it in my book. After break in the boat is back to 5800 rpms and 71mph with full tank...

Update Mercury came back with two options reman powerhead at cost or new powerhead at cost. I declined both and in the process of having the powerhead rebuilt. Thanks everyone that has tried to help....

Update still no word from Mercury but shop estimated $2700 to strip engine down re-sleeve cylinder and put it back together. That seems pretty reasonable to me so either way hopefully back up under...

Savage I was thinking the same thing. These should have been indexed or Pinned from the factory. This issue is way more common that I would have suspected.

Yep Don that is the lesson learned. Just hoping they might but won’t be angry if they don’t. Kinda on me as far as that goes. Life lessons not always cheap

Yes Joe I think the dealership is going to try to talk to Mercury on my behalf. They are definitely not obligated to step in and help out here but hoping that they might. If not I will be sending it...

As promised rotated sleeve #2 cylinder. Question should I re-sleeve all the cylinders while it is being done?

I was lucky enough to have a leaking powerhead gasket and rotated sleeve both on the same engine. What are the odds? Should I go get my numbers now for the lottery?lol
I have a photo of the Rotated...
